If you’re gearing up to take the Professional Engineering/PE exam, one of the first questions on your mind is probably: How long is this test going to take?
After all, pass rates vary wildly, ranging anywhere from 81% for Agricultural and Biological Engineering to a bleak 42% for Petroleum Engineering. You’re likely already a little on edge, depending on your engineering discipline.
Luckily, knowing what to expect on exam day can ease some of that pre-test jitters and help you plan your study schedule more effectively. So, let’s dive into the details and clear up everything about the length of the PE exam, including breaks, structure, and how your chosen engineering discipline plays a part.
Key Takeaways
- Exam Length: The PE exam lasts 8 hours, split into two 4-hour sessions with a scheduled lunch break in between.
- Exam Format: It’s a computer-based test featuring multiple-choice questions tailored to your chosen engineering discipline.
- Year-Round Availability: You can schedule your exam date year-round at approved NCEES exam sites near you.
- Discipline Specific: Content varies by particular engineering discipline, like civil, electrical, or computer engineering.
- Prep Matters: Using review courses or well-organized study materials aligned with exam specifications can boost your chances.
What Is the PE Exam Anyway?
Before we talk about how long the PE exam is, a quick refresher might help. The PE exam is a big step toward becoming a licensed professional engineer. After passing the Fundamentals of Engineering (FE) exam and gaining some work experience, the PE exam tests your ability to practice engineering in a particular engineering discipline—like civil, electrical and computer, mechanical, or others.
The exam specs can vary depending on your field, but it’s always designed by the National Council of Examiners for Engineering and Surveying (NCEES), so you know it’s standardized and fair.
How Long is the PE Exam? The Basics
The PE exam is eight hours long. Yep, that’s a full day of intense brainpower! Here’s how it breaks down:
- Morning Session: 4 hours
- Scheduled Break: 1 hour for lunch
- Afternoon Session: 4 hours
You get a solid break in the middle to recharge, grab a bite, and maybe even do a little stretching (highly recommended).
What Does the Exam Look Like?
The PE exam is a computer-based exam, which means it’s taken at an NCEES-approved exam site with a computer workstation. No more lugging around tons of paper or worrying about messy handwriting! The exam consists of multiple-choice questions, tailored to your chosen engineering discipline.
- The morning session typically covers breadth topics—general knowledge you should know across your discipline.
- The afternoon session usually dives deeper into the practice of engineering for your specialty.
For example, if you’re taking the civil engineering exam, the afternoon might focus on your chosen civil discipline, like structural, geotechnical, or water resources. If you’re a PE electrical candidate, your afternoon could cover electrical power or computer engineering specifics.
Why Does the Length Matter?
You might be thinking, “Eight hours? That’s a marathon!” And you’re right, it definitely is. The length matters because:
- You need stamina and focus to get through the entire day without burning out.
- Planning your own study materials and exam prep schedule around that time frame makes a big difference.
- Knowing the structure will help you manage your time during the exam. Don’t spend too long on any one question!
How Is the PE Exam Different From the FE Exam?
If you’re an undergraduate student or early in your career, you might already know about the FE exam. The FE is shorter (about 6 hours) and more general. It’s your first step to becoming a professional engineer. The PE exam is the next big hurdle, more specialized and longer.
Another big difference: the FE exam is also computer-based but tends to cover more general engineering concepts, while the PE exam focuses on your particular engineering discipline and the real-world application of that knowledge.
Scheduling Your Exam Date and Site
One great thing about the PE exam is that it’s offered year-round at approved test centers across the country. You’ll pick an exam date and exam site that works best for you.
- Since it’s computer-based, the NCEES exams have flexible scheduling compared to older paper-based tests.
- You can check the NCEES examinee guide for all the official details about scheduling and what to expect on exam day.
Make sure you pick a test site that’s comfortable for you and plan to arrive early on exam day so you can settle in.
Tips for Surviving the 8-Hour PE Exam
Eight hours is a long time to be sitting, so here are some quick tips I’ve found helpful or heard from others who’ve passed:
- Practice with full-length exams. Simulate the real thing so your brain and body get used to the length.
- Take the scheduled break seriously. Eat a filling lunch, but nothing too heavy. Stay hydrated!
- Manage your time per question. Don’t get stuck on any tricky ones—mark and come back if you can.
- Bring approved reference materials and know how to use them quickly. This can save precious time.
- Get a good night’s sleep before exam day. Trust me, coffee only goes so far.
What About Review Courses and Study Materials?
You might wonder if PE prep courses make a big difference in preparing for the exam. The answer? For many, yes.
- Review courses can help you focus on exam specifications for your chosen engineering discipline.
- They offer practice questions, tips, and strategies specifically for the Professional Engineering exam.
- Some are NCEES-approved, meaning they align closely with the official exam content.
If you prefer self-study, make sure your own study materials cover all the necessary topics and give you enough practice with timed tests.
Final Thoughts
So, how long is the PE exam? It’s an eight-hour challenge, split into two four-hour sessions with a lunch break. It’s designed to test your skills in your particular engineering discipline, from civil engineering exam candidates to those taking the PE electrical or computer-based tests.
Knowing the length helps you prepare mentally and physically, so you can stay sharp on exam day. Don’t underestimate the importance of pacing yourself and having a solid study plan.
If you want my honest advice, start early, find study materials that match your coursework and discipline, and take plenty of practice exams under timed conditions. You’ve got this!
